FoRAGE - Zero available prey yet non-zero consumed

[marknovak]

The following datasets have rows where the count of available prey is zero and yet the number of eaten prey is greater than zero.

I am removing these rows.

Many of these appear to be the result of densities < 1 being rounded to 0 or 1.

Should check exported summary of InsufficientTreatments.txt after zeroes of #7 are dealt with.

The issue is fixed by use of Scientific notation in orginal csv

[marknovak]

Two remaining datasets have 0 prey available (but also have 0 prey eaten in these treatments):

762 Hansen and Nielsen 1997 1668 Quinn et al 2003

The latter is a field study, so is understandable. The former is a replicated lab study. Looking at the paper, the datapoint definitely looks like it’s at zero in Fig. 1A. The main text (pg. 188) also indicates that they used a zero prey density. Confusingly, Fig.1B suggests it should not be a zero. Moreover, the entered value of SE is non-zero for prey eaten. The confusion of Fig.1B aside, is seems that the SE should be set to 0. (I don't see a measurable SE in the figure 1A either.)
