TraceMinBase constructor with eigenproblem, solver utilities, and parameter list of solver options.

This constructor takes pointers required by the eigensolver, in addition to a parameter list of options for the eigensolver. These options include the following (in addition to those of TraceMinBase):

• "Block Size" - an int specifying the block size used by the algorithm. This can also be specified using the setBlockSize() method.
• "Num Blocks" - an int specifying the maximum number of blocks allocated for the solver basis.
