Speed profile calculation function

Several speed parameters must be set for motion function. Some-
times parameters conflict in a speed profile. For example, if a very
fast speed and a very short distance is inputed, there is no profile
for these parameters. In this situation, the motion library will main-
tain the acceleration and deceleration rate attempting to automati-
cally lower the high speed originally inputed to form a feasible
speed profile. The following diagram shows this concept.

The motion library has a series of functions that can be used to
find the actual speed profile developed from the original com-
mands from the user.
