start is incorrect

[nsheff]

I keep getting errors with going out of bounds and realized that it's both printing a start in the header, and also printing actual counts for those, leading to errors.
See:

nsheff@zither:~/code/uniwig$ cat test3.bed 
chr1    7       10
chr1    8       12
chr1    9       15

nsheff@zither:~/code/uniwig$ ./uniwig test3.bed 1 1
fixedStep chrom=chr1 start=7 step=1
0
0
0
0
0
1

This wig should have 1 as its first entry, not a bunch of 0s, since the header says start=7.

I can fix, it seems, this by commenting out 2 lines that print 0s until the first position.
