Estimate phi in a flexible manner as guided by lframe

obj 
a matrix whose rowSums are used to estimate phi

glm.frm 
a formula. If omitted

fitting phi  the probabilities that a sonicant lands in a particular
bin  is crucial to estimating theta, then number of sonicants when
more than one lans in a bin. bins may be defined by sonicant lengths
when there is just one sample. When there are multiple samples, then
one may wish to estimate phi separately for each
one. lframe$strata
indicates separate sample and the default
glm.frm
will fit each one separately.
a vector whose sum is 1.0 with one element for each row of obj
