Various mesh related information for a parallel run. Upon construction, constructs all info using parallel communication.
Requires:
The shared point and edge addressing calculates addressing for points and edges on coupled patches. In the 'old' way a distinction was made between points/edges that are only on two processors and those that are on multiple processors. The problem is that those on multiple processors do not allow any transformations and require a global reduction on the master processor.
The alternative is to have an exchange schedule (through a 'mapDistribute') which sends all point/edge data (no distinction is made between those on two and those on more than two coupled patches) to the local 'master'. This master then does any calculation and sends the result back to the 'slave' points/edges. This only needs to be done on points on coupled faces. Any transformation is done using a predetermined set of transformations - since transformations have to be space filling only a certain number of transformation is supported.
The exchange needs
