Wrong example on the FIRMR reference page

Hi.

IMHO, there are several misstakes on the FIRMR reference page (https://software.intel.com/en-us/node/529034).

1) ippsFIRMR_Init_32f - redundant "_" in function name

2) Wrong sizes of pDlySrc and pSrc. They are more than necessary.
In the case when upFactor==1 size of pSrc must be "downFactor*(numIters-1)+1" and size of pDlySrc must be "tapsLen - 1". But in example if we change upFactor to 1 then size of pSrc becomes equal to "downFactor*numIters" and size of pDlySrc becomes equal to "tapsLen"

Correct me if I'm wrong.

Some addition. In the chapter "Description" there is a line:
"y(0)=h(tapsLen-1)*d(1)+h(tapsLen-2)*d(2)+...+h(1)*x(0)+h(0)*x(1)".

It should be :
"y(1)=h(tapsLen-1)*d(1)+h(tapsLen-2)*d(2)+...+h(1)*x(0)+h(0)*x(1)"
