Manchester to standard logic decoder

Converts a manchester encoded string to its standard logic equivalent.

MANCHESTER2BIN(inputData) decodes a manchester serial sequence to its corresponding binary value.

Decoding is done according to G.E. Thomas' convention (high-to-low '01' = '1', low-to-high '10'= 0), assuming LSB first transmission.

Syntax: decodedData = MANCHESTER2BIN(inputData)

Where:
inputData = string with binary values which length must be EVEN, with the MSB at at the left-most position (index = 1)
decodedData = string with binary values which length is half of inputData with the MSB at the left-most position

If the inputData sequence is not a valid manchester code MANCHESTER2BIN
will return an empty string.

Example:
>>decodedData = manchester2bin('01011010')

decodedData =
1100
