Add available workflows by category

Closes #149 (closed)

Ewoks

There is little metadata associated to a workflow: category, id and label With these fields we should be able to find which workflows are suitable for a set of datasets. We can rely on the workflow id giving a certain meaning. For instance: technique_beamline_scanType_cardinality_workflowName

Example:

mx_id30a-1_collection_1_integration : integration is suitable for a single dataset which technique is mx, collected on id30a-1 which scanType is collection

mx_*_*_1_integration: integration is suitable for any dataset which technique is mx

mx_*_*_*_integration: integration is suitable for any number of datasets which technique is mx

Presentation

When one or multiple datasets are selected then a list of workdlows is shown

One a workflow is clicked then the input parameters are displayed in a from:
