+!------------------------
+!
+! Unit test framework for FORTRAN.  (FoRtran UnIT)
+!
+! This package is to perform unit test for FORTRAN subroutines
+!
+! The method used most are: assert_true, assert_equals
+! 
+! Coding convention:  
+!   1) All methods must be exposed by interface.  i.e. interface init_fruit
+!   2) Variable and methods are lower case connected with underscores.  i.e. init_fruit, and
+!      failed_assert_count

+!>  \brief Element mass matrix (3-noded triangular)
+!!
+!!  \param  iel   Element number
+!!  \param  emass Element mass matrix
+!!
+!!  This routine performs the following integration:
+!!
+!!      \int_A N^T * rho * N dA
+!!
+!!  where N is the shape function matrix, rho is the material density,
+!!  and A is the area of the element. The routine uses the technique of
+!!  Gaussian quadrature to numerically evaluate the integral. However,
+!!  note that the integration points and weights are selected such that
+!!  the exact integral is obtained. Consequently, only the usual floating
+!!  point error is present in the result of the integration.

+!!  \param unit_name  Name of unit test (for FRUIT)
+!!  \param test_A   Test banded symmetric matrix
+!!  \param test_b   Test right-hand-side vector
+!!  \param test_x   Vector for solution

+!!  \param toler    Tolerance on solution (floating point error)
+!!
+!!  This test solves a system of equations, test_A*test_x = test_b, for
+!!  test_x in the general case for a banded symmetric positive definite
+!!  matrix, test_A. The right-hand-sides, test_b, are computed through
+!!  multiplication of test_A and test_x. That is, the input is
+!!  test_b = test_A*test_x. Therefore, the expected output from the solver
+!!  with inputs test_A and test_b is the original vector test_x. In
+!!  particular, this test solves the system twice. On the second attempt,
+!!  the branch of the linear solver that reuses the decomposition of
+!!  test_A is activated.
