avoidZero

Get rid of zeros in a numeric vector before taking 
the logarithm of them. We basically replace the "zeros" with a negligible small 
 value in order to avoid NaN upon the log-transformation.

To run data analysis for enzyme-link immunosorbent assays (ELISAs).
Either the five- or four-parameter logistic model will be fitted for data of single ELISA.
Moreover, the batch effect correction/normalization will be carried out, when there are more than one batches of ELISAs.
