V1.14b

Fixed a few problems with energy loss calculations
in the Material class. The electron density was
being calculated incorrectly, causing errors in
the calculation of the range.

Modified Material::Beta2 to make it relativistic.
Also included a new function named Material::Energy
to calculate the relativistic energy given an input
beta value.

Added a new class named Particle. Particle contains
the particle name, A, Z, and a range table. This
makes it easier to setup a particle without worrying
about generating range tables.

Added a new tool named 'range'. The range tool will
calculate particle ranges in an input material.
V1.14c

Added mass variable to Particle class.

Fixed energy loss problems for particles moving
through detectors.

Added new detector type "dual". This allows detectors
to detect both ejectile and recoil particles at the
same time.

Added a pulse analyzer and a pulse viewer tool.

Tested elastic scattering simulations.
