Some barcodes lead to unitialized data seg fault

[wltrimbl]

idemp seg faults on line 299 (writing the .decode file) for some valid input files.

This happens whenever the input has at least one barcode that is too far from any of the barcodes. NNNNNNNNN triggers this problem for testing.

This happens because the loop that sets readBarcodeIdx[i] and readBarcodeMis[i] does not set an initial value for readBarcodeIdx and the conditionals enclosing the statements that assign readBarcodeIdx are sometimes not satisfied.

Good catch, didn't think of this situation

Is there any fix for this type of problem? I noticed several instances of NNNNNNNNNNNN in my indexing reads and I keep getting a segmentation fault error.

@wltrimbl provided a fix.
