Added new properties to the algorithm.

Refs #7229
Fixed indentation of the test code.

Refs #7229
Reduced the number of files loaded for tests.

It's was quite slow already, but I am going to add more tests.

Refs #7229
Added tests for functionality to be implemented.

Obviously failing for now.

Refs #7229
Fixed the indentation of the ApplyDeadTimeCorr code.

Refs #7229
Code clean-up regarding usage of a namespace.

Refs #7229
Methods for applying dead time correction.

Refs #7229
New algorithm to group detectors using info from Muon Nexus.

Refs #7229
Make the algorithm retrieve workspaces from a group, not from ADS.

Otherwise I couldn't use child algorithm to modify workspace before
it gets used.

Refs #7229
Use the new algorithm to apply auto-grouping.

It means I can apply dead time correction before grouping happens.

Refs #7229
Improve tests a bit.

Refs #7229
Make grouping functions to return output workspaces.

Refs #7229
Code to apply dead time correction.

Is passing the tests.

Refs #7229
Moved all DTC applying code to functions.

Refs 7229
Add an include for std::accumulate.

Refs #7229
Added extensions to test files so they can be found.

Refs #7229
Tie all the properties to their widgets.

This make the whole thing less error-prone and gives me a list of
all the property widgets.

Refs #7229
Unified the code for handling Browse buttons.

Will be easier to add another one now.

Refs #7229
Added DTC widgets to the UI.

Refs #7229
Code for connecting DTC widgets to algorithm properties.
