DMProjectFunctionLabelLocal#
This projects the given function into the function space provided by the DM, putting the coefficients in a local vector, setting values only for points in the given label.

Developer Notes#
This API is specific to only particular usage of DM
The notes need to provide some information about what has to be provided to the DM to be able to perform the computation.
