Tensorial notation II: tensor lagrangian function + ndimf vector

[jose-antonio-torres]

Current status:

Main classes/functions:

Outline of the solution

• Convert fValues to vector
• Implement ndimf as a vector
• Make all Algebraic Tests pass
• Adapt all override methods in BaseFunction
• Remove default ndimf = 1 in domain function
• Add ndimf to Materials
• Repair projectors
• Clean Lagrangian Function + FeFunction
• Adapt al Expand & extraDims
• Lagrangian function bug in plot
