Calculates body mass form cane (1987), foraging distande from Greenleaf et al. (2007) and tongue length from Cariveau et al. (2015) using intertegular distance values (IT).

1	ITconverter(IT, family, type = "all", mouthpart = "all")

`IT`	A vector of bee intertegular spans (IT) measurments in cm.
`family`	a vector of bee families. Only implemented 5 out of the extant 7 families: "Andrenidae", "Apidae", "Colletidae", "Halictidae", "Megachilidae".
`type`	The type of foraging distance desired. Options are "all", "Maximum homing distance", "Typical homing distance", "Maximum feeder training distance", "Maximum communication distance". See details in Greenleaf et al. 2007.
`mouthpart`	The mouthpart you are interested in. Options are "all", glossa", "prementum" and "tongue" (i.e. gloss + prementum)

A dataframe with bee body masses (gr), tongue length (mm) and foraging distance (km) is returned for each bees species. Abreviations as follows: foraging_distance.mhd: Maximum homing distance foraging_distance.thd: Typical homing distance foraging_distance.mfd: Maximum feeder training distance foraging_distance.mcd: Maximum communication distance
