/*! \class Table
|
|
\brief STK table lookup class.
|
|
|
|
This class loads a table of floating-point
|
|
doubles, which are assumed to be in big-endian
|
|
format. Linear interpolation is performed for
|
|
fractional lookup indexes.
|
|
|
|
An StkError will be thrown if the table file
|
|
is not found.
