- QtSearchView was split into QtSearchView and QtSearchBox.
- QtSearchBox contains all Qt elements and can use them purely
- QtSearchView forwards calls from the SearchController to QtSearchBox
- Searching is initiated with MessageSearch to the SearchController
- Autocompletion is initiated with MessageSearchAutocomplete to the SearchController
- The search field is able to create filter queries by only giving autocompletions for the last token in the query
- For named tokens the search field adds their token ids to the query in the form of "A,25" for faster lookup

Having the TestStorage as static field of the TestSuites caused problems in test startup, because the TestSuites are
instantiated globally and for some reason the programm has trouble allocating memory when initializing the SearchIndex.
This change stores each Token name in the separate singleton class Dictionary. The Dictionary gives each saved word an
Id and thereby avoids duplicated names. E.g if the constructor method "Graph::Graph" is stored then the word "Graph"
only appears once in memory.
The class SearchIndex is now responsible for the name hierarchy and is instantiated by the Storage. The SearchIndex
builds the name hierarchy using SearchNodes, each holding a Dictionary string reference of the name it holds. E.g if the
names "math::ceil" and "math::floor" are added to the SearchIndex then 3 nodes get created, the SearchNode "math" will
hold the two childs "ceil" and "floor".
The hierarchical graph creation functionality got split off from Graph into the new subclass StorageGraph. The
StorageGraph creates nodes with a passed SearchNode pointer of the name it represents in the SearchIndex. Thereby the
StorageGraph reuses the hierarchical information in the SearchIndex and can create nodes much quicker by avoiding node
searches and name comparisions.
The name information is now stored in the Nodes via the TokenComponentName class, which is subclassed into
TokenComponentNameReferenced and TokenComponentNameCached. The StorageClass creates nodes with the component
TokenComponentNameReferenced, which holds a pointer to the SearchNode instance holding the name. This allows for
retrieving the full name of the node, without using other Nodes int the Graph, which might not be present. If the Node
is copied then the component changes to a TokenComponentNameCached, which holds the full name as a string, so the
memory in the Storage doesn't have to be accessed anymore.
TokenComponentSignature is now only holding an Id of the signature string saved in the Dictionary, which speeds up the
signature comparison. A follow-up will change saving the whole signature as string to reusing the wordIds it is
consisting of.
Lastly the SearchIndex holds basic fuzzy search functionality. A passed query gets compared down the SearchNode
hierarchy as long as matches for each letter are found. Matches must contain all letters of the query. The search is
case-insensitive. If letters are found in front positions, next to each other or written in uppercase they are weighed
higher in the match ranking. The character ':' is also interpreted and found, although the '::' delimiter is not stored.
E.g. the query "m:l" used on the example above will return both "math::floor" and "math::ceil", but "floor" is ranked
higher because the 'l' appears closer to the start.
