spott: Calculate the central tendency of an image object
In devSJR/micR: Image processing with micR

Selects objects based on a specific moment parameter, where currently only majoraxis (recalculated as micro meter) is used.

1	spott(img.raw, img.pp, img.moment, quantile = 0.03, ...)

`img.raw`	is the raw image that will used for the detection of the nucleus
`img.pp`	is input of the type img.processor object (see img.processor micR)
`img.moment`	is an computeFeatures.moment object (see computeFeatures.moment EBImage)
`quantile`	is a value to define the values removed by quantile filtering
`...`	is the input for the img.selector subroutine (see img.selector micR)
