Enable analyser launch on a datagroup (eg, result of parameter-space exploration)

The result of a parameter space exploration is a bunch of timeseries with the
same underlying properties: sample rate; number of nodes; etc. As they have the
same structure, it makes sense to be able to run the same analysis on all of
them, so, it would be very useful that if when a datatype group contains many
instances of one datatype then analysis applicable to that datatype could be
accessed when the group is selected (data-structure and operations pages),
configured once and then run in the same configuration on all the instances
within the group resulting in a group of the results (much like the
DatatypeMeasure does currently as a result of the parameter space exploration).
