/** Epetra Finite-Element CrsMatrix. This class provides the ability to
    input finite-element style sub-matrix data, including sub-matrices with
    non-local rows (which could correspond to shared finite-element nodes for
    example). This class inherits Epetra_CrsMatrix, and so all Epetra_CrsMatrix
    functionality is also available.

    It is intended that this class will be used as follows:
    <ul>
    <li> Construct with either a map or graph that describes a (non-overlapping)
    data distribution.
    <li> Input data, including non-local data, using the methods
    InsertGlobalValues(), SumIntoGlobalValues() and/or ReplaceGlobalValues().
    <li> Call the method GlobalAssemble(), which gathers all non-local data
    onto the owning processors as determined by the map provided at
    construction. Users should note that the GlobalAssemble() method has an
    optional argument which determines whether GlobalAssemble() in turn calls
    FillComplete() after the data-exchange has occurred. If not explicitly
    supplied, this argument defaults to true.
    ***NOTE***: When GlobalAssemble() calls FillComplete(), it passes the
    arguments 'DomainMap()' and 'RangeMap()', which are the map attributes
    held by the base-class CrsMatrix and its graph. If a rectangular matrix
    is being assembled, the correct domain-map and range-map must be passed to
    GlobalAssemble (there are two overloadings of this method) -- otherwise, it
    has no way of knowing what these maps should really be.
    </ul>

    Sub-matrix data, which is assumed to be a rectangular 'table' of
    coefficients accompanied by 'scatter-indices', can be provided in three
    forms:
    <ul>
    <li>Fortran-style packed 1-D array.
    <li>C-style double-pointer, or list-of-rows.
    <li>Epetra_SerialDenseMatrix object.
    </ul>
    In all cases, a "format" parameter specifies whether the data is laid out
    in row-major or column-major order (i.e., whether coefficients for a row
    lie contiguously or whether coefficients for a column lie contiguously).
    See the documentation for the methods SumIntoGlobalValues() and
    ReplaceGlobalValues().

    Important notes:
    <ol>
    <li> Since Epetra_FECrsMatrix inherits Epetra_CrsMatrix, the semantics of
    the Insert/SumInto/Replace methods are the same as they are on
    Epetra_CrsMatrix, which is:
    <ul>
    <li>InsertGlobalValues() inserts values into the matrix only if the graph
    has not yet been finalized (FillComplete() has not yet been called). For
    non-local values, the call to InsertGlobalValues() may succeed but the
    GlobalAssemble() method may then fail because the non-local data is not
    actually inserted in the underlying matrix until GlobalAssemble() is called.
    <li>SumIntoGlobalValues() and ReplaceGlobalValues() only work for values
    that already exist in the matrix. In other words, these methods can not be
    used to put new values into the matrix.
    </ul>
    </ol>
