##
## Construct a BilinearForm previously imported from ufl.
##
## The compulsory arguments are:
## @itemize @bullet
## @item @var{my_problem} the name of the problem to solve.
## @item the FunctionSpace @var{U} and @var{V} where the problem is defined.
## @end itemize
##
## The optional arguments are the @var{coefficient_1}, @var{coefficient_2}
## which specify the parameters for the BilinearForm as stated in the ufl file.
## They can be either a Constant, a Function or an Expression.
