add_units

<p>Units are added to support molecular weight and mEq/L conversions.  Units are
named with the unit, an underscore, and the chemical species in lower case.
Examples are <code>"g_ammonia"</code>, <code>"mol_ammonia"</code>, and
<code>"Eq_ammonia"</code>.  Species with units are all species inputs for the
<code>equil2()</code> function.</p>

Saturation of ionic substances in urine is calculated based on
sodium, potassium, calcium, magnesium, ammonia, chloride, phosphate, sulfate,
oxalate, citrate, ph, and urate.  This program is intended for research use,
only.  The code within is translated from EQUIL2 Visual Basic code based on
Werness, et al (1985) "EQUIL2: a BASIC computer program for the calculation
of urinary saturation" <doi:10.1016/s0022-5347(17)47703-2> to R. The Visual
Basic code was kindly provided by Dr. John Lieske of the Mayo Clinic.
