+Identify core features in table
+--------------------------------
+
+Identify "core" features, which are features observed in a user-defined
+fraction of the samples. Since the core features are a function of the
+fraction of samples that the feature must be observed in to be considered
+core, this is computed over a range of fractions defined by the
+`min_fraction`, `max_fraction`, and `steps` parameters.
+
+Parameters
+----------
+table : FeatureTable[Frequency]
+    The feature table to use in core features calculations.
+min_fraction : Float % Range(0.0, 1.0, inclusive_start=False), optional
+    The minimum fraction of samples that a feature must be observed in for
+    that feature to be considered a core feature.
+max_fraction : Float % Range(0.0, 1.0, inclusive_end=True), optional
+    The maximum fraction of samples that a feature must be observed in for
+    that feature to be considered a core feature.
+steps : Int % Range(2, None), optional
+    The number of steps to take between `min_fraction` and `max_fraction`
+    for core features calculations. This parameter has no effect if
+    `min_fraction` and `max_fraction` are the same value.
