CFxp: Added m_fracBits to store position of binary point
CFxp: Added toFloat() for conversion to complex<float>
CFxp: Fixed bug in toFloat() when m_fracBits is 63 or 64
CFxp: Updated truncation and rounding to support fractional bits
CFxp: Assignment checks for matching binary point position
CFxp: Added binary point support to + operator
CFxp: Added binary point support to * operators
CFxp: Removed >> and << operators
CFxp: Added binary point support to scalar * operator (required initial binary point support in FixedPoint class)
CFxp: Added toDouble() method
CFxp: Added static method quantize() to create CFxp from floating point type
